摘要
本文以动力松弛法为基础,提出效率更高的求解非线性问题的修正的自适应动力松弛方法(modified adaptive Dynamic Relaxation method:简称:maDR方法)本文将该方法用于分析圆薄板的大挠度弹塑性弯曲以及塑性分叉问题,均取得了良好效果,本文的研究表明,maDR方法具有广阔的应用前景。
Based on the Dynamic Relaxation method(DR method), the paper proposes a modified adaptive Dynamic Relaxation method(maDR method) which is much more efficient than the former in solving highly nonlinear problems. It is then applied to analysing the elastic-plastic bending of circular plates in large deflection and their following wrinkling, and leads to very good results. The present investigation shows that the maDR method proposed here possesses vast vistas of application.
